Hi, I'm Shiva Kar - a Software Engineering (BCA) student from Hojai, Assam.

My engineering philosophy is built on "monstrous efficiency"—mastering deep technical fundamentals rather than chasing framework bloat. I am architecting a rigorous foundation in systems programming (C) to understand how the machine works under the hood, while building highly scalable, enterprise-grade web applications using Java, Spring Boot, and PostgreSQL.

I strictly separate my architectural concerns: Java for heavy backend logic, React/TypeScript for clean frontends, and Python strictly for utility automation.

My Long-Term Roadmap: Mastering the Java Backend Stack -> Securing a Top-Tier MCA via NIMCET -> Architecting Distributed Systems at MAANG.

When I am not writing server logic, you can find me building indie games in Godot and Blender, maintaining a 120+ WPM typing speed, or sticking to a highly disciplined 6-day strength training split. Performance isn't just about code; it's a lifestyle.

Building a minimal Unix shell entirely from scratch in C to master process execution and memory management. Features a custom lexer for tokenization, a syntax parser, and an execution engine handling fork/exec, system calls, and I/O redirection.

C System Calls Process Management Memory Allocation

Implementing a basic web server using raw POSIX sockets to serve static files. Designed to bridge the gap between low-level operating systems and backend web infrastructure.

C Networking Sockets

Building a simplified Git clone in C to understand content-addressable storage, blob and tree objects, and commit history internals.
